- 1. Double ultrasound signal capturing
Our ultrasonic measuring system captures the signal with two sensors, in both directions simultaneously, for spatially precise recording
- 2. Measurement hardware acceleration
Devices based on SharpFlow measurement technology run on a sophisticated and proven hardware logic.
- 3. High-resolution vector measurement diagrams
Based on the multi-layered recorded values, the measurement software is able to render particularly precise and sharp graphics.
Ultrasound technology
Two diagonally opposite ultrasound transducers alternately send and receive ultrasonic waves. Without any air flow inside the breathing insert, the transit time of the ultrasound waves is the same in both directions.
Any air flow inside the insert will accelerate the waves in one direction and decelerate in the other. The difference between the transit times of the ultrasonic waves allows to calculate the flow.
Flow and gas density are calculated from the measured transit times, allowing changes in the concentration of the exhaled gases to be determined directly and at the same time with the respiratory volume.
All other factors (gas properties, humidity and temperature) are the same for both directions
and cancel each other out.
Precision & Resolution
- The high sampling resolution is a prerequisite for reliable determination of flow
- No noticeable resistance during breathing - helpful for respiratory restrictions
Calibration free
- Less time-consuming in daily work
- No faulty measurements due to incorrectly calibrated or uncalibrated pneumotachs
- Designed without moving or sensitive parts
No detours
- No substitute parameters for flow necessary (e.g. differential pressure)
- Direct flow measurement based on digital measurement technology
- High measuring resolution with 1,000 single measuring points per second - developed and patented by GANSHORN
Humidity and temperature irrelevant
- Not affected by changing ambient conditions or humidity of breathing air
- Immediately ready for use after cleaning – no long drying time
Easy cleaning
- No moving parts or inaccessible corners
- Breathing insert is made of one piece and can be replaced quickly and easily
- Suitable for disposable or permanent breathing insert
